Self-aligned fabrication process for silicon quantum computer devices
T. M. Buehler, R. P. McKinnon, N. E. Lumpkin +6
We describe a fabrication process for devices with few quantum bits (qubits), which are suitable for proof-of-principle demonstrations of silicon-based quantum computation. The dev…
Magnetic susceptibility of the normal-superconducting transition in high-purity single-crystal alpha-uranium
J. L. O'Brien, A. R. Hamilton, R. G. Clark +9
We report complex ac magnetic susceptibility measurements of a superconducting transition in very high-quality single-crystal alpha-uranium using microfabricated coplanar magnetome…
Density dependent spin polarisation in ultra low-disorder quantum wires
D. J. Reilly, T. M. Buehler, J. L. O'Brien +6
There is controversy as to whether a one-dimensional (1D) electron gas can spin polarise in the absence of a magnetic field. Together with a simple model, we present conductance me…
Quantum measurement of coherence in coupled quantum dots
H. M. Wiseman, Dian Wahyu Utami, He Bi Sun +4
We describe the conditional and unconditional dynamics of two coupled quantum dots when one dot is subjected to a measurement of its occupation number using a single electron trans…
Many-body spin related phenomena in ultra-low-disorder quantum wires
D. J. Reilly, G. R. Facer, A. S. Dzurak +7
Zero length quantum wires (or point contacts) exhibit unexplained conductance structure close to 0.7 X 2e^2/h in the absence of an applied magnetic field. We have studied the densi…
Anomalous Carrier Lifetime Enhancement and Effective Mass Discontinuity Observed during Magnetic-field-induced Subband Depopulation in a Parabolic Quantum Well
G. R. Facer, B. E. Kane, R. G. Clark +1
In GaAs/AlGaAs parabolic quantum wells, subbands are depopulated by a magnetic field in the well plane. A small additional perpendicular field induces Shubnikov-de-Haas (SdH) oscil…
